1. Meta-Phenomics

The response of plants to their environment can best be described by dose-response curves. Unfortunately, for most plant traits these curves are not known, notwithstanding a wide range of publications. The first target of my work is to reconstrThe response of plants to their environment can best be described by dose-response curves. Unfortunately, for most plant traits these curves are not known, notwithstanding a wide range of publications. The first target of my work is to reconstruct these dose-response curves for a range of growth-related traits (RGR, photosynthesis, respiration, water relations, chemical composition, anatomy, morphology) in response to 12 of the most important a-biotic environmental factors.uct these dose-response curves for a range of growth-related traits (RGR, photosynthesis, respiration, water relations, chemical composition, anatomy, morphology) in response to 12 of the most important a-biotic environmental factors.´- Review on biomass allocation- Biomass allocation: effect of size and speciesFor more information see www.metaphenomics.org

2. Leaf Mass per Area (LMA)

LMA (or alternatively SLA) is one of the important traits underlying variation in growth rate between species, and strongly affected by various environmental factors such as light and temperature. What are the factors underlying variation in LMA (with special focus on leaf anatomy) and what are the consequences thereof?- Review on LMA- Relation with anatomy
